There are a number of possible reasons for this:

• At the time of the program, there were more recordings scheduled than available tuners. watchmi recorded the programs that it thought you liked the best. In the future, you can resolve such scheduling conflicts in the Scheduled Recordings dialog.
• It is possible that at the scheduled recording time, the TV tuner was not connected or in use by another program
• It is also possible that the power to the PC was off, so Windows was not able to activate the recording function.
